TOKYO (AP) - Officials at Japan's tsunami-ravaged nuclear plant say there's no immediate sign of new problems after a magnitude-7.4 aftershock rattled the nation's eastern coast.
A nuclear safety official says the workers at the Fukushima Dai-Ichi Plant are safe but does not know if they have been evacuated.
The Metereorological Agency issued tsunami warnings and advisories for a stretch of more than 300 miles of the northeastern coast from Aomori prefecture in the north to Ibaraki prefecture in central Japan, just north of Tokyo.
Announcers on Japan's public broadcaster NHK told coastal residents to run to higher ground and away from the shore.
